4624459c84 drm/amdgpu: add gang submit frontend v6
Allows submitting jobs as gang which needs to run on multiple engines at the
same time.

All members of the gang get the same implicit, explicit and VM dependencies. So
no gang member will start running until everything else is ready.

The last job is considered the gang leader (usually a submission to the GFX
ring) and used for signaling output dependencies.

Each job is remembered individually as user of a buffer object, so there is no
joining of work at the end.

v2: rebase and fix review comments from Andrey and Yogesh
v3: use READ instead of BOOKKEEP for now because of VM unmaps, set gang
    leader only when necessary
v4: fix order of pushing jobs and adding fences found by Trigger.
v5: fix job index calculation and adding IBs to jobs
v6: fix typo found by Alex

cdc7893fc9 drm/amdgpu: use job and ib structures directly in CS parsers
Instead of providing the ib index provide the job and ib pointers directly to
the patch and parse functions for UVD and VCE.

Also move the set/get functions for IB values to the IB declerations.

No function change, just move a bunch of definitions from amdgpu.h into
separate header files.
